7. Outlaw Star
Aired in Japan 1998 and on Toonami in 2001, the series follows Gene Starwind and his buddy James "Jim" Hawking from backwater colony planet to the secrets of the universe. The spaghetti-style western anime is great since it follows the story of a gutsy underdog getting to the top of the outlaw universe. Spaceships, great cast of a crew, and awesome story line reminding one of the ecstasies of gold surely will get you hooked.
